Black Bears Extensively Use Trans-Canada Wildlife Crossings to Look for Mates

A recent study conducted by Montana State University has revealed that Black and Grizzy bears are trying to meet the opposite sex members on both sides of the Trans-Canada Highway. They are extensively using wildlife crossing to meet their love.

Scientists in the past have been apprehensive about the fact that due to fencing on the highway in Banff National Park, animals might not be able to mate with members present on the other side and this may result in inbreeding.

In their study, Parks Canada had found that due to fencing and about 44 crossings, there was a drastic fall of 80% in the wildlife mating, they were still unsure whether the animals used crossings to meet their love or not.

The researchers of Montana State University have now found that one black bear male used crossing for breeding and mated with five different females of his species and is father of at least 11 baby bears.

"He certainly has found that he has increased his own breeding opportunities by having access to both sides of the highway," said Michael Sawaya, Lead Author of the study. However, the researchers haven't been able to determine yet, whether the crossing has given some of the animals, better chances of breeding.

The bears prefer to use crossings in comparison to the tunnels to reach other parts of the park.

The study has been published in the journal Proceedings of the Royal Society B on Tuesday.
